Wrapped long lines in an error message, and fixed two bugs:

1) rndc would crash if rndc.conf could not be read
2) rndc running in named.key mode required a working
DNS to resolve the default server name "localhost",
causing a chicken-and-egg problem when using rndc
to fix a broken DNS.  Fixed by changing the default
to 127.0.0.1.  This will probably offend some IPv6
people.
